Domenico and other interested folks,

Read what G3LTF has said about Galileo and 23cm EME:
http://www.batc.org.uk/club_stuff/G3LTF_Galileo.pdf

He paints not quite so bad a picture as Bob and John do.  If you think a
handful of "potential" ham satellite users are potentially effected, the
large (2nd most popular EME band, today) 23cm EME population are watching
this keenly.  I have several thousand dollars invested in my future 23cm
EME station...and I will just been a medium size station.  There several
>10m EME dishes operating in Europe...those are not cheap.  I suspect Ham
radio on L-band will not go down without controversy and a significant
fight.  Yes, I understand the multi-B$ industry "owns" the radio spectrum,
but I think this is gotten a bit hysterical and negative in view.  I
suspect EME will survive on 23cm and perhaps satellite uplink use (with
some compromise).

At this point it is all speculation (even with engineering analysis).  I am
glad the decision is to fly a mode-L Rx.  I predict it will be usable in
the early years of Eagle (at least).
73's,
